In the comp.os.cpm newsgroup, one of the posts referred to wanting to
know the geneology of MDOS (Micropolis Dos.) That led to the fact the
disks were 16 hard sector disks ... which led to the interfacing for the
Micropolis 100 TPI disks drives. Is the controller specific to the
controller or can the drive be interfaced to any controller? I suspect
the controller and drive are a pair but don't know for sure.
